Definition of Auger effect in US English:

Auger effect


  • A process in which an electron in an outer shell of an atom makes a transition to a vacancy in an inner shell. The energy gained is transferred to an electron that escapes from the atom.

    • ‘First an electron is captured into a bound state and a bound electron is excited (inverse Auger effect).’
    • ‘A brief history of the discovery of the Auger effect is given, which is followed by a short description of some of the fields in which this discovery has had a major impact.’
    • ‘This process of resonant photon absorption accompanied by electron emission forms a resonant Auger effect or resonant Auger Raman scattering.’
    • ‘The second is the Auger effect, by which the hole left by the excited core electron is filled by an outer electron.’
    • ‘This is known as the Auger effect or autoionization since the ion has self-ionized after the photoionization event.’


1930s: named after Pierre V. Auger (1899–1993), French physicist.
